The first recreational cannabis to be legally bought in Canada was purchased at midnight on Wednesday (02:30 GMT) on the eastern island of Newfoundland amid queues of hundreds of people.
Canada has become the second country after Uruguay to legalise possession and use of recreational cannabis.
Medical marijuana has been legal in the country since 2001. But concerns remain, including about the readiness for police forces to tackle drug impaired driving.
Information has been sent to 15 million households about the new laws and there have been public awareness campaigns.
Ian Power, from the town of St John’s began queuing at 20:00 local time so he could “make history”. Newfoundland is half an hour ahead of the next province to the west.
A number of analysts are predicting a shortage of recreational marijuana in the first year of legalisation as production and licensing continues to ramp up to meet demand. — BBC
